IMPROVEMENT IN FEED-WATER HEATERS.

Specification forming part of Letters Patent No. 122,204, dated December 26, 1871.

Specification describing certain Improvements Fig. 2. Fig. 2 is a horizontal section taken on the line y y, Fig. 1.

A represents the two Wide corrugated or zigzag-shaped sides of the holder; B, the narrow sides; (3, the ends; and D, the pipe-connection. These parts comprise a holder for Water to be heated for supplying boilers.

I have devised this form of holder with special reference to the facility with which it can be molded andcast, so as to enable me to provide a cheaper heater with large heating-surface in a small compass than can be made of wrought metal or of tubes; but itmay be made of rolled sheet metal.

Having thus described my invention, I claim as new and desire to secure by Letters Patent The metallic feed-water heater, having two zigzag sides, A, narrow sides B, and ends 0, constructed as described.

The above specification of my invention sign ed by me this 19th day of October, 1871.

WILLIAM E. WALSH.
